Hello! I have a question.. something weird with my mails. Since 2 weeks my WHMCS doesnt send mails to customers. I get a summary mail every day after cronjob (invoices created, overdue etc.) but no mails to the customers get send. They get no Invoices, overdues, Password forgotten etc. I have already tried PHP Mail, SMTP with 3 different servers etc. But this mails already worked and I dont have changed anything.. What could be happend? Also the system email massage log shows no mail. WHMCS doesnt try to send a mail althought someone request password reset or an invoice get created??
